End Electrical Nightmares & Restore Your GM Truck’s Brain
Are you battling bizarre and frustrating electrical problems in your GM truck, van, or SUV? One minute the power windows work, the next they don’t. The security light flashes randomly, the interior lights have a mind of their own, or worse, the vehicle won’t start. These aren’t just annoyances; they’re signs that your vehicle’s Body Control Module (BCM) is failing. The BCM is the central command center for your vehicle’s body electronics, and when it goes bad, it can create a cascade of unpredictable issues. This pre-programmed BCM is the definitive, reliable solution to get your vehicle back to 100% functionality.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing BCM is the likely culprit:
- Power windows, door locks, or mirrors operating intermittently or not at all.
- Interior dome lights or dashboard lights staying on or not turning on.
- Erratic behavior from the radio or climate control system.
- The security system (Passlock/VATS) preventing the engine from starting.
- False warning lights or messages on the instrument cluster.
- Communication errors with diagnostic scan tools (e.g., DTC U1000).
Instead of wrestling with a used part from a salvage yard or paying steep dealership prices for programming, this module offers a direct path to a lasting repair. We take the guesswork out of the equation by programming this specific 2002 Yukon XL 1500 BCM to your vehicle’s unique VIN before it even ships. This ensures compatibility and a much smoother installation process.
Expert Insight: Why a Pre-Programmed Module is the Smart Choice
The BCMs in these early 2000s GM vehicles have seen countless heat cycles and vibrations over two decades. Internal solder joints can crack and electronic components can degrade, leading to the erratic failures you’re seeing. Grabbing a module from a junkyard is a gambleโit might have the same age-related issues or fail shortly after installation. Our solution provides a fully inspected and tested module that is then flashed with the latest stable GM software updates for your VIN. This not only restores original function but can also improve on it by addressing software bugs that were present in the original programming. It’s the most reliable and efficient way to get your truck back on the road and working correctly.

Post-Installation Requirements
While this module is programmed for your vehicle, some models may require simple relearn procedures after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed by a professional with a capable scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed on some models to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior and exterior lighting, the security system, wipers, and often communicates with the radio and climate control systems.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to program the BCM with the exact software and settings your vehicle was built with. This includes options like keyless entry, power seat types, and other specific features, ensuring everything works correctly right out of the box.
My original part number isn’t on the list, but my vehicle is. Will it work?
GM often uses several interchangeable part numbers for the same component. If your make, model, and year are listed in the compatibility chart, this module will function as a proper replacement, even if the number on your original part is slightly different from the primary number 15063578.
Can I install this myself?
For many DIYers with moderate experience, this is a manageable job. The BCM is typically located under the steering column or center dash. The main challenge is accessing it. However, because some post-installation procedures (like the airbag sync) may require a professional-grade scan tool, you should be prepared to seek help from a qualified mechanic if needed.
What happens if the airbag light comes on after I install it?
This is a known possibility. The BCM and the airbag system (SDM) are linked for security. If the light appears, it simply means they need to be re-synchronized. A repair shop with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How does the one-year replacement warranty work?
If the module fails within one year of the purchase date, we will provide a replacement unit. This gives you confidence and protection for your purchase. Please retain your proof of purchase for any warranty claims.
